Ⅰ. Material:

RINGS & BALLS vacuum degassed, high carbon chromium bearing steel GCr15 is the standard material for precision bearing rings and balls. The material has uniform specification as AISL 52100(America)DIN100 Cr6(German), JISSUJ2(Japan)

These deep-groove ball bearings are suited to parts of devices that require high-speed rotation, low-friction torque and low vibration/noise in order to make such devices smaller, lighter-weight and thinner.

Ⅱ. Feature : high precision bearings have less internal friction and can work with smaller starting torque, which means a lower power consumption.

Ⅲ. Application: Hard disc drives, stepping motors, fan motors, encoders, DVD spindles, small motors, pinch rollers, etc.

Ⅳ. Specification

• A deep groove ball bearings is the must popular type of rolling-element bearing composed of an outer race ball, an inner race and a bearing cage.and the race dimensions are close to balls dimensions.
• The materials for producing ball bearing are variety including stainless steel,chrome steel and silicon nitride and more with a simpler construction comparing with other ball bearing, deep groove bearings are suitable for large quantity production
• The function of deep groove ball bearings is to reduce rotation friction.those balls between outer race and inner race help avoid two flat surfaces rotating on each other thus to achieve the purpose of lowering down friction coefficient
• Additionally, deep groove ball bearings are primarily used to support radial loads; supports both radial and axial loads is also possible
• Deep groove ball bearings can be used in wide range of applications.

1. Firstly, they can de used in industrial transmission mechanical products.
2. Miniature bearings are widely used in household appliances, toys, electric power tools, car motors and other fields. With optimal design, high reliability heat treatment, precision manufacturing processes and high-grade grease, these products perform better on reliability, vibration and noise levels than standard products making them more suitable for electric motor applications. These products can also be applied to most gearbox applications as well.
3. Thirdly, our bearing are ideal for electrical motor with good quality and excellent performance. Because of their high precision, high rotating speed, high reliability, low friction and low noise, they are widely used in areas of machine tools, measuring instruments, office machinery, household appliances, various types of electric motors, industrial automation control, etc.
